Furthermore the available energy density of batteries for a given battery size and the difficulty of recharging possibilities limits the life cycle of sensor nodes. Multiple access methods will help to expand the operational life cycle of sensor nodes by reducing their power consumption. The focus of this work is to evaluate multiples access methods wake-up solutions for wireless sensor applications. A custom demonstration platform to perform theses evaluations and measurements has been developed. The current measurements have shown that multiple access wake-up methods in conjunction with switching of not needed components will extend the life cycle of sensor nodes immense.","PeriodicalId":403208,"journal":{"name":"2008 2nd Annual IEEE Systems Conference","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125184794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But system level approach is a more promising way for power saving, especially in embedded system design. A design of portable radio frequency identification (RFID) reader, using system level power reduction method and working at 433/868/915 MHz ISM frequency, is presented in this paper. The system embeds a SOC (system on chip) peripheral driving circuits to simplify the complex driving circuits of traditional LCD display. Besides, a developed software tool helps to improve the system performance, such as the address matching, anti-collision, checking, identification, real time calculation and data display. The proposed system has advantages of simple structure, low cost, and low power loss.","PeriodicalId":403208,"journal":{"name":"2008 2nd Annual IEEE Systems Conference","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133036963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This model must be designed at an abstract level, hiding system details. However, it must represent any subsystem or its components at any level of specification details as needed. In order to model such a system, we will need to combine various models-of-computation (MOC). MOCs provide a framework to model various algorithms and activities, while accounting for and exploiting concurrency and synchronization aspects. Along with supporting various MOCs, a modeling environment should also support a well developed library. In this paper, we have explored and compared various system modeling environments. MLDesigner is one such modeling environment that supports a well developed library and integrates various MOCs. We discuss the process of system modeling with MLDesigner. We further present an abstract model of a network-on-chip (NoC) in MLDesigner and show latency results for various customizable parameters for this model.","PeriodicalId":403208,"journal":{"name":"2008 2nd Annual IEEE Systems Conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133312336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In medical applications, reliability and ubiquity must be guaranteed by new communication technologies in order to favour their adoption. Ensuring a satisfactory quality of service and a high degree of availability requires a reliable delivery system that optimally brings together several wireless access systems and medical-based platforms into an efficient trial product to satisfy operational needs. This paper proposes a novel system architecture to support adaptive real-time medical applications, possibly multimedia-based, over various wireless technologies. The system addresses several issues associated with the successful operation of applications running over heterogeneous networks. First, it defines a layer of abstraction to isolate the applications from the actual transport system. Second, it uses a message-based protocol to improve the reliability and security of the communications over different access systems. Finally, it includes adaptation mechanisms for various system statuses. A real-life healthcare application capable of transmitting voice, video and medical data simultaneously is used for validation. Experimental results are reported that demonstrate the viability of the approach.","PeriodicalId":403208,"journal":{"name":"2008 2nd Annual IEEE Systems Conference","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114710546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are many areas of research in pervasive computing such as context-awareness, device and network heterogeneity issues, power consumption, and connectivity. Each area intends to address problems such as how devices interpret their environment, and how devices communicate with each other. While there is much potential for developers to create pervasive applications from scratch, it is much more likely that they are able to reuse existing applications and documentation for mobile devices. This paper addresses the specific problems of porting pervasive applications on mobile devices in general as well as the unique problems presented by mobile devices which restrict implementation methods. It proposes a framework based on model driven engineering concepts for developing software for restrictive pervasive systems. The paper also considers the implications of the preliminary framework on the iPhone, which forces developers to work through its Safari browser.","PeriodicalId":403208,"journal":{"name":"2008 2nd Annual IEEE Systems Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124239273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has led to growing reliance on increasingly interoperable and interdependent systems that combine multiple organizational and functional capabilities to achieve and overarching mission. This is the motivation for developing systems- of-systems, enterprise systems, and even extended enterprise systems. This paper focuses on the engineering of this class of systems: a process that demands consideration of increasing scale, the rapid pace of change of the underlying technologies, the complexity of system interactions, and, perhaps most important, shared ownership and control. We hypothesize that engineering these systems is inherently different from engineering large-scale but essentially deterministic systems. Decisions about the system(s) under development have to consider not only the technical and programmatic dimensions but also the political, operational and economic contexts. This paper presents a diagnostic tool for profiling complexity and uncertainty in large scale system engineering developments and provides some lessons learned from its application. On the basis of these insights, we propose an approach to tailoring engineering and acquisition strategies and practices to the specific circumstances at hand.","PeriodicalId":403208,"journal":{"name":"2008 2nd Annual IEEE Systems Conference","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123282780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The emergence of new operational concepts like network-centric operations, greatly expanded use of joint and combined operations, and rampant growth in system complexity has led to the prevalence of interoperable systems of systems as the preferred solution to providing operational capability. Unfortunately, the \"programmatics\" (i.e., the relationships between-and orchestration of activities across-all lifecycle aspects, including program management, system acquisition, development, transition/ deployment, sustainment, and operational use) are not well understood in systems of systems and, as a result, system-centric approaches are frequently employed, often with disastrous consequences. To better understand the root causes for these problems, and identify potential mitigation strategies, this paper introduces some simple guidelines-in the form of a set of laws, or meta-behavioral descriptions and a corresponding reasoning framework-to assist program managers with systems-of-systems programmatics.","PeriodicalId":403208,"journal":{"name":"2008 2nd Annual IEEE Systems Conference","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121371461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
